T @ZZ whom t may concern/.-

Be it known that I, HENRY ENGEL, a subject of the Emperor of Austria-Hungary, and a resident of New York, inthe county and State of New York, haveinvented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

The object of my invention is to provide a device which may be applied to the'neckof an ordinary bottle and when so applied cannot be removed without either destroying the device or the bottle and to place in said device means whereby liquid may be withdrawn from the bottle, but cannot be injected into the same, so that all fraudulent relling of a bottle is prevented and those who purchase a liquid of a special brand put upin a bottle provided with my improvements may know that the contents of said bottle are genuine. This object I accomplish by means of a cap which is secured to the bottle-neck by springs or other suit-able means which prevent its removal, and in this cap is placed a valve which prevents the refilling of the bottle.

For a more detailed description of one embodiment of my invention reference is to be had to the accompanying drawings, forming a part hereof, in which- Figure 1 is a longitudinal section of my improved cap when applied to the neck of a bottle. Figs. 2, 3, and 4 are detailed views of disks immediately below 'the lines 2 2, 33, and 4 4, respectively.

Corresponding parts in all the gures are denoted by the same reference characters.

The bottle 1, to which myimprovement may be applied, maybe of any suitable shape and size and is provided with a neck 2, which is notched at its upper end to form the mouth of the bottle and to form shoulders 3. The cap 4 is provided with a cylindrical lower portion 5, which fits over the bottle-neck 2 and is provided with spring-fingers 6, soldered or otherwise secured thereto, which engage the v shoulders 3 and prevent removal of Athe cap after it has been placed in position. While of any instrumentinto the bottle-neck or valve mechanism, whereby the valve may be kept from its seat. The said diaphragms are connected by means of a centrally-located square rod 11, on which is placed a spring 12, the upper end of which rests against the lower surface of the diaphragm 8 andthe lower end of l which rests on the upper surface' of a disk 13, which has an angular bore 14, through which lherod 11 passes and prevents the said disk 13 from having any angular movement. The

disk 13 is provided with perforations in'which are inserted rubber plugs 15, which register with the openings 9 and completely close the same whenever the spring 12 holds the disk 13 to its seat.

The upper end lot" the cap 4 may be made in vany suitable way and given any shape that is desired, although it is preferably made with a cylindrical opening 16, in which may be inserted a stopper 17, which is preferably covered at its lower end with tin-foil 18.

The cap 4 may be made of any suitable material,although I preferably construct it of alu minium,and the disk 13 is preferably made of lead,so that it will have considerable weight in proportionto its size, although other suit able material may be employed.

The operation and advantages of my invention will be'readily understood. The liqf uid is iirst inserted into the bottle 1, and when said bottle is filled lthe cap isv placed over the neck thereof until the springs 6 engage the shoulder 3 and x the capto the bottle. When the contents of the bottle are withdrawn,the bottle is inverted, and the pressure on the liquid against the rubber plug 15 and the weight of the-valve 13 are suliicient to overcome lthe resistance of Athe spring 12 and place the valve on its seat,

thereby permitting the liquid to pass ont through the passages 9 and from thence through the passages 10 and out through the opening 16. When no more liquid is to be 5 poured from the bottle,it is restored to its up I5 arrangement as herein described and illustrated, as it is manifest that Variations and modifications may be made in the features of construction and arrangement in the adaptation of the device to various conditions of zo use Without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variation and modification as properly fall within the scope of my invention and the terms of 5 the following claims.

Having thus described my invention, I

claim and desire to secure by Letters Patent- 1. In a non-rellable bottle or similar article, a bottle-neck, a cap secured thereto, diaphragme in said cap connected by a square rod, and a spring on said rod, a non-rotatable valve on said rod which is pressed to its seat by means of the said spring.

2. In a non-rellable bottle, a flange on said neck, a bottle-cap fitting over said neck and provided with spring-fingers to engage the said flange whereby said cap is held in place,diaphragms in said cap above said neck, and a reciprocatably mounted non-rotatable valve for permitting the flow of liquid in one direction only, said valve comprising in its construction a disk with rubber' inserted therein.

In testimony whereof I have signed my name in the presence of the subscribing witnesses.

HENRY ENGEL.
